• The genotypes tested showed varying levels of glycosylation, with the majority having significant arabinoside and galactoside derivative content. Specific genotypes, such as Legacy, Ira, and Sampson, had notably low amounts of glucosidic derivatives. Conversely, other genotypes, including Onslow, wild blueberry (WBB), bilberry, SHF2B1-21:3, and LB composite, exhibited glucosidic derivative amounts that were equal to or greater than that of their arabinoside and galactoside derivatives.

• Hyperoside, a beneficial flavonoid galactoside found in both medicinal and edible plants, plays a critical role in plant growth, self-defense, and breeding, as well as in human health through its numerous pharmacological properties. However, the biosynthetic pathway of hyperoside in plants, including its original source, Hypericaceae, has not been systematically elucidated yet.
